Download GTDInbox – Firefox add‑on for Gmail productivity

Overview

GTDInbox is a free Firefox add‑on that re‑imagines Gmail as a task‑focused workspace. Designed for users who live by the Getting‑Things‑Done (GTD) methodology, the extension adds a lightweight command box that lets you label, archive, preview and prioritize emails without ever leaving your inbox. After installing the add‑on, a short setup wizard asks you to create a few standard labels such as S/Action and S/Finished.

These labels become the backbone of the workflow, turning ordinary messages into actionable items that can be sorted by priority, status or project. While the concept promises a faster, more organized Gmail experience, the real‑world usability hinges on how intuitively the popup interface can be mastered. Early adopters report a mixed experience: the ability to assign priority tags and open multiple compose windows simultaneously is praised, but the learning curve can feel steep compared with Gmail’s native interface.

GTDInbox aims to be a secure, regularly updated tool that works on any platform where Firefox runs – Windows, macOS, Linux, and even Android or iOS devices that support the desktop version of the browser. If you’re searching for a way to boost Gmail’s task management without paying for a separate CRM, GTDInbox offers a compelling, albeit occasionally puzzling, solution.

Key Features & Benefits

• One‑click task labeling: Quickly apply GTD‑style labels (S/Action, S/Waiting, S/Finished) from the popup command box.
• Priority tagging: Assign high, medium or low priority flags to any email, enabling instant sorting and filtering.
• Inline preview & edit: View the content of an email, edit its subject line, or modify labels without opening a new tab.
• Bulk actions: Select multiple messages and perform archive, delete, or label operations in a single click.
• Multi‑window composition: Open several compose windows at once, each linked to a different task‑oriented email.
• Secure OAuth integration: Uses Google’s official OAuth flow, ensuring that your credentials never leave the browser.
• Automatic updates: Receives regular patches via Firefox’s add‑on marketplace, keeping the tool compatible with Gmail’s UI changes.
• Cross‑platform support: Works wherever Firefox runs – Windows, macOS, Linux, and even on mobile browsers that support desktop extensions.

These features translate into tangible productivity gains for power users. By converting every incoming message into a potential task, GTDInbox reduces the mental overhead of switching between Gmail and external to‑do lists. The priority system lets you focus on urgent items first, while the bulk actions save time when processing newsletters or project updates. Moreover, the secure OAuth authentication means you can trust the extension with your Google account without exposing your password. For teams that already rely on GTD principles, GTDInbox acts as a natural extension of their workflow, embedding task management directly into the email client they already use every day.

Installation, Usage & Compatibility

Step‑by‑Step Installation

1. Open Firefox and navigate to the GTDInbox add‑on page.
2. Click Add to Firefox and confirm the permissions request.
3. After the download finishes, Firefox will prompt you to restart the browser – do so.
4. When you open Gmail, a brief setup wizard appears. Click Create Default Labels to automatically add S/Action, S/Waiting, and S/Finished to your Gmail account.
5. Optionally, customize the label names in Gmail’s label settings if you prefer different terminology.

Using the Popup Command Box

Once the extension is active, a small icon appears in Gmail’s toolbar. Clicking the icon opens the command box. From here you can:

• Press A to assign the S/Action label to the selected email.
• Press P to set a priority level (1‑high, 2‑medium, 3‑low).
• Use the V key to preview the message without leaving the inbox view.
• Hit R to archive or D to delete instantly.

The interface is keyboard‑centric, which speeds up workflow for users comfortable with shortcuts. For visual learners, the popup also displays checkboxes for each label, allowing mouse‑based selection. All changes are saved instantly to your Gmail account, so you can switch devices and see the same task status across platforms.

Operating System Support

GTDInbox runs wherever Firefox is supported: Windows 10/11, macOS 12+, various Linux distributions, and Android/iOS browsers that can run desktop extensions (via user‑agent tricks or Firefox Focus). Because it is a browser‑based tool, there is no separate installation for mobile; you simply enable the add‑on in Firefox on the device and the same features become available.
